mbed_official 205:c41fc65bcfb4 12 ##### How to use this driver #####
mbed_official 205:c41fc65bcfb4 13 ==============================================================================
mbed_official 205:c41fc65bcfb4 14 [..]
mbed_official 205:c41fc65bcfb4 15 The common HAL driver contains a set of generic and common APIs that can be
mbed_official 205:c41fc65bcfb4 16 used by the PPP peripheral drivers and the user to start using the HAL.
mbed_official 205:c41fc65bcfb4 17 [..]
mbed_official 205:c41fc65bcfb4 18 The HAL contains two APIs categories:
mbed_official 205:c41fc65bcfb4 19 (+) Common HAL APIs
mbed_official 205:c41fc65bcfb4 20 (+) Services HAL APIs

mbed_official 205:c41fc65bcfb4 100 [..] This section provides functions allowing to:
mbed_official 205:c41fc65bcfb4 101 (+) Initializes the Flash interface, the NVIC allocation and initial clock
mbed_official 205:c41fc65bcfb4 102 configuration. It initializes the source of time base also when timeout
mbed_official 205:c41fc65bcfb4 103 is needed and the backup domain when enabled.
mbed_official 205:c41fc65bcfb4 104 (+) de-Initializes common part of the HAL.
mbed_official 205:c41fc65bcfb4 105 (+) Configure The time base source to have 1ms time base with a dedicated
mbed_official 205:c41fc65bcfb4 106 Tick interrupt priority.
mbed_official 205:c41fc65bcfb4 107 (++) Systick timer is used by default as source of time base, but user
mbed_official 205:c41fc65bcfb4 108 can eventually implement his proper time base source (a general purpose
mbed_official 205:c41fc65bcfb4 109 timer for example or other time source), keeping in mind that Time base
mbed_official 205:c41fc65bcfb4 110 duration should be kept 1ms since PPP_TIMEOUT_VALUEs are defined and
mbed_official 205:c41fc65bcfb4 111 handled in milliseconds basis.
mbed_official 205:c41fc65bcfb4 112 (++) Time base configuration function (HAL_InitTick ()) is called automatically
mbed_official 205:c41fc65bcfb4 113 at the beginning of the program after reset by HAL_Init() or at any time
mbed_official 205:c41fc65bcfb4 114 when clock is configured, by HAL_RCC_ClockConfig().
mbed_official 205:c41fc65bcfb4 115 (++) Source of time base is configured to generate interrupts at regular
mbed_official 205:c41fc65bcfb4 116 time intervals. Care must be taken if HAL_Delay() is called from a
mbed_official 205:c41fc65bcfb4 117 peripheral ISR process, the Tick interrupt line must have higher priority
mbed_official 205:c41fc65bcfb4 118 (numerically lower) than the peripheral interrupt. Otherwise the caller
mbed_official 205:c41fc65bcfb4 119 ISR process will be blocked.
mbed_official 205:c41fc65bcfb4 120 (++) functions affecting time base configurations are declared as __Weak
mbed_official 205:c41fc65bcfb4 121 to make override possible in case of other implementations in user file.
